The messy quest to replace drugs with electricity

In the early 2010s, electricity seemed poised for a hostile takeover of your doctor’s office. Research into how the nervous system—the highway that carries electrical messages between the brain and the body— controls the immune response was gaining traction.

And that had opened the door to the possibility of hacking into the body’s circuitry and thereby controlling a host of chronic diseases, including rheumatoid arthritis, asthma, and diabetes, as if the immune system were as reprogrammable as a computer.

To do that you’d need a new class of implant: an “electroceutical.” These devices would replace drugs. No more messy side effects. And no more guessing whether a drug would work differently for you and someone else. In the 10 years or so since, around a billion dollars has accreted around the effort. But electroceuticals have still not taken off as hoped.

Now, however, a growing number of researchers are starting to look beyond the nervous system, and experimenting with clever ways to electrically manipulate cells elsewhere in the body, such as the skin.

Their work suggests that this approach could match the early promise of electroceuticals, yielding fast-healing bioelectric bandages, novel approaches to treating autoimmune disorders, new ways of repairing nerve damage, and even better treatments for cancer. Read the full story.

Why bigger EVs aren’t always better

SUVs are taking over the world—larger vehicle models made up nearly half of new car sales globally in 2023, a new record for the segment. 

There are a lot of reasons to be nervous about the ever-expanding footprint of vehicles, from pedestrian safety and road maintenance concerns to higher greenhouse-gas emissions. But in a way, SUVs also represent a massive opportunity for climate action, since pulling the worst gas-guzzlers off the roads and replacing them with electric versions could be a big step in cutting pollution. 

It’s clear that we’re heading toward a future with bigger cars. Here’s what it might mean for the climate, and for our future on the road. Read the full story.

The big story

House-flipping algorithms are coming to your neighborhood

April 2022

When Michael Maxson found his dream home in Nevada, it was not owned by a person but by a tech company, Zillow. When he went to take a look at the property, however, he discovered it damaged by a huge water leak. Despite offering to handle the costly repairs himself, Maxson discovered that the house had already been sold to another family, at the same price he had offered.

During this time, Zillow lost more than $420 million in three months of erratic house buying and unprofitable sales, leading analysts to question whether the entire tech-driven model is really viable. For the rest of us, a bigger question remains: Does the arrival of Silicon Valley tech point to a better future for housing or an industry disruption to fear? Read the full story.
